e LB M ?ATTERSQ1\T,- o DULUTH, MINNESOTA- LAM Application filed September 30, 1913.

To all whom it may concern Be it known that. I, GILBERT PATTERSON, a citizen of the United States, and a resident of Duluth, county of St. Louis, and

State of Minnesota, have invented certainnew and useful Improvements in Lamps, of which the following is a full, clear, and ex: act description.

This invention relates more particularly to a lamp for burning a heavy congealable material as wax or paraffin.

One of the principal objects of the inven: tion is to provide a simple and efficient lamp in which the material may be quickly heated in order that it may be properly supplied to the wick to produce" a light and in which the heat may be properly conducted as the light is burning to the receptacle containing the material and thereby liquefy the material to cause the same to be supplied continuously to the wick.

Other objects of the invention are to pro vide simple and efficient means for holding the material serving as a pro-heater or initial heating means; to provide simple and eflicient means which is adapted to hold a supplementary or feed wick in such a way as to supply the lighting wick; to provide a simple and eflicient heat conducting device or devices adapted to be acted upon by the flame of the lamp and so constructed that carbon is not likely to be deposited thereon; and to provide a simple and efficient re- Hector and means for supporting the same on the lamp body or receptacle.

Another object of the invention is to provide a lamp which is not expensive to manufacture and which is so constructed that the parts may be readily removed and are ac cessible for repairs and the like.

A further object of the invention is to provide a lamp in which the pro-heating means as well as the wick or wick supporting and holding means and the feeding wick may be detachably held to the receptacle bod A still further object of the invention is to provide means whereby two wicks. one a feed wick and the other a lighting wick, may be so supported and arranged within the receptacle that they will remain in constant contactand the material when reduced to a fluid state fed to the wicks.

With these and other objects in view, the invention will be hereinafter more particularly described with reference to the accoma Specification of Letters Patent.

panying drawings, which form a part of this specification, and will then be pointed out in the claims at the end of the description.

In the drawings, Figure 1 is a vertical section of one form of lamp embodying my invention. Fig. 2 is a plan view. Fig. 3 is a vertical section taken on the line III-7H1 of Fig. 1, showing the burner preheating means and wick supporting and heat-conducting means detached from the lamp body. Fig.- 4 is a transverse section taken on the line Ive-IV of Fig. 3. Fig. 5 is a vertical section through a form of lamp somewhat similar to that" shown in Fig. l and in which a reflector is shown, and also in which only one of the wicks is detachable with the pre-heating means; and Fig. 6 is a plan view of the lamp shown in Fig. 5.

The receptacle or body 10 may be of any suitable form or construction and on one side thereof may have a handle 11. The upper part of the receptacle or body 10 may be provided with a filling opening, as 12, and adapted to fit in this opening is a detachable cap or cover 13. The cap or cover 13 may be formed substantially cup-shaped as shown and has a part thereof adapted to be engaged by the inwardly extending flanges which may be depressed from the upper portion of the body 10.

A receptacle or member 15 substantially cup-shaped in form and provided with a flared outer end is adapted to be detachably held in an opening 16 in the upper end of the body 10, and surrounding said opening is a flange 17 forming a substantial support and rest for the receptacle or member 15. The receptacle 15 extends some distance within the body or receptacle 10 and is provided with an elongated slot in which is adapted to fit an elongated tubular member 18 forming a burner and through which the upper portion of the lighting wick 19 is adapted to extend. The burner 18 may be variously constructed and may be provided with a plurality of openings 20 at each side thereof to adapt the melted wax, paraffin or other material in the member or receptacle 1.5 to pass to the wick 19 and to supply the same at the initial or preliminary burning and heating of the wax and until the larger body in the receptacle 10 has been heated sufficiently to properly supply the wicks. The wick 19' is long enough to extend within the body or receptacle 10 and normally rests and remains in contact/with a feed wick 21. These Wicks are held by supports or members 22 and'23 and said members form heat conductors to assist in melting the heavy material about the same. The conductor 22 is somewhat shorter than the conductor 23 and both conductors have apertures or openings 24 to adapt the fluid burning material to pass therethrough. "These conductors do not entirely encircle the wicks and one of said conductors, as the conductor 23, may be provided with flanged edges, as at 25, to serve as a better means for guiding the lighting wick 19. The conduc tors 22 and 23 are curved and at their upper ends are flared and provided with flanges 26 which are adapted to be secured to the bottom of the cup-shaped member 15 by rivets 27 and in such a way as to rigidly hold the conductors to the member 15 so that said conductors with the wicks and the member 15 as a whole may be removed from the receptacle 10.

It will be evident that by placing the proper quantity of waX or paraflin or other material in the cup-shaped member 15 and lighting the same, the heat will melt the wax sufficiently to supply the wick 19 in order that the same may be lighted either independently or by the light from the preliminary heating material. In thus burning the preliminary heating material, the metallic parts of the burner, the body of the receptacle 15 and the conductors 22 and 23 are also heated and in this way the wicks are properly supplied with the material and the wicks are thus permitted to burn until the light is extinguished.

As a supplementary or additional heatconducting means, I provide two heating devices 28 and 29. These devices are similar in construction and each have a substantially T-shaped body 30, the upper part of which extends transversely of the upper end of the wick and at a short distance therefrom. The heating device or member 29 is somewhat shorter than the member or device 28 and both members are flared outwardly somewhat and then inward toward the light. the purpose of the device 27 being shorter than the member 28 is that otherwise it might obstruct the light from the wick. Each of the devices 28 and 29 has a flange 31 and these flanges are secured to the bottom of the receptacle or member 15 by the rivets 27 which also hold the conductors 22 and 23 to said member or receptacle. The devices 28 and 29 are so constructed and formed that they are not likely to hold carbon deposit thereon and are so arranged that the heat from the lighting wick as well as the heat from the preliminary heating means may be quickly conveyed to the receptacle 15 and to the heat conductors 22 and 23.

Figs. 5 and 6 show a construction somewhat similar to that shown in Figs. 1 to 4. In this form, the main body or receptacle 32 is somewhat more tapering and has a spout or tubular part 33 at one side thereof. In the tubular part 33 is a cup-shaped receptacle or member 34 in which is arranged an elongated tubular burner 35, which, as in Fig. 1, projects somewhat above the upper edge of said member 34. The receptacle 34 is adapted to hold suflicient wax, paraflin or other material for preliminary heating purposes and held to the receptacle and to the burner 35 is a heating device 30. This device 36 flares inwardly at the rear of the burner and has an elongated part 37 and may be substantially T-shaped as in the other form and may have its lower por tion curved and formed U-shaped to adapt it to be secured both to the receptacle or member 34 and to the burner. A wick guide and conductor 38 is rigidly held to the bot tom of the member 34 and extends downwardly within the body 32 so as to rest against the lighting wick 39. The wick 39 remains in constant contact with the feed wick 40 and this feed wick is supported by a plate or guide 41 which serves primarily as a conductor for the heat. The plate or member 41 rests against a rod or part 42 and at its upper end is provided with a vertical portion 43 which is secured by rivets or otherwise to a part of the tubular portion 33 serving to conduct the heat therefrom.

The body 32 has a handle 44 and a filling opening 45 which is adapted to be closed by a cover 46. The cover 46 may be hinged, as at 47, and may have guides 48 secured thereto. These guides are adapted to receive the base 49 of a support 50 which car ries a reflector 51 of any suitable form. The reflector as thus constructed may be readily detached from the cover 46 or attached thereto by simply sliding the same along the guides 48.

In the form of lamp shown in Fig. 5, only one of the conductors 8 is removable with the receptacle or member 34 though it will be readily understood that both may be made removable as shown in Fig. 1. It will be further understood that the reflector shown in Fig. 5 may be also used in connection with the lamp shown in Fig. 1, and that other features of one lamp may beinterchangeably used or constructed so as to be interchangeably used with the other if desired.

Having thus described my invention, I claim as new and desire to secure by Letters Patent l. A device of the character described, comprising a body for holding the main fuel supply, a cup adapted to hold priming fuel, a tubular burner in said cup, a wick extending through said burner, and heatconducting means engaging the Wick and held to the bottom of said cup.

2. A device of the character described, comprising a body for holding the main fuel supply, a cup detachably held to said body and adapted to hold priming fuel, a tubular burner in said cup, a Wick extending through said burner, and heat-conducting means engaging the Wick and said cup.

3. A device of the character described, comprising a body for holding the main fuel supply, a cup held to said body and adapted to hold priming fuel, a perforated burner tube in said cup, a Wick extending through the burner tube, and a heat conductor held to said cup.

4.
